Funny you should mention that... I haven't really dug in yet but I was looking for a good reason to brush up on LaTeX and have been on a math reading tear lately. I couldn't find any other attempts so if I make any progress I'll edit or comment on this with a link.
FYI, the three notebooks are available in PDF form here: http://www.math.tifr.res.in/~publ/ramanujan.html. This warms my heart.
